DETROIT, MI -- Batman could end up in a Batsuit made out of Kryptonite for at least a few scenes if reports end up accurate about a soon-to-be-released toy that's believed to be affiliated with the "Batman vs. Superman: Dawn of Justice" film.

The comic book fan website Newsarama.com and Variety both report that Mattel, DC Comics and Warner Bros. have a deal in place to produce toys affiliated with the movie, other related superhero films and TV shows.

Production crews who are working on the film in Metro Detroit are referring to "Batman vs. Superman" as "Sage and Milo."

Scenes were shot earlier this week at a building in Pontiac that's expected to serve as villain Lex Luthor's LexCorp headquarters.

The "Batman vs. Superman" film is considered the most expensive movie to ever be shot in Michigan (the project budget is $131 million, according to the Michigan Film Office) and could be released the same day as the untitled "Captain American 3" film backed by Disney.

The Michigan Film Office awarded "Batman vs. Superman" filmmakers last summer an incentive of $35 million for in-state work.

The film office expects the movie to create hundreds of jobs for crew members and about 6,000 jobs for extras.
